2007 Silverado Oil Pump
I know there are a few gear heads on here and thought i would get some thoughts. I have a 2007 Silverado with 190,000 miles and it appears the oil pump just went on me. Did some research and on my truck it does not appear to be an easy job to fix. Been quoted about $1100 to fix it since they have to drop the pan and do a ton of other work and most of the cost seems to go towards labor at about 7-8 hours. I am torn between fixing it and getting a new truck. I still like my truck but with the amount of miles it has i am wondering if this is the beginning of the end. Any thoughts appreciated.
It works 60% of the time all the time......

That's less than 2 months payments and the truck ain't worth much broken down. I would pay the piper.
You might want to get a second opinion.
I suggest you consider your options carefully.

Shade tree trick on something with that kind of miles (don't listen to me)
Drain the oil refill with diesel, run for about a minute with the diesel in the oil pan.
Drain and refill with a slightly thicker oil then the factory recommendation.
Or call junk yards. I had a V6 delivered for my wifes caravan for $650 it had 60K miles on it.
Took 2 cases of beer 2 pies of pizza and a couple of friends to change it out in a day.
Check the pressure with a mechanical gauge
It may be a bad sending unit
My Suburban went down to 2 psi but still ran
Some trucks have a fuel pump shutoff set at about
7-10 psi.
New sending unit cured the problem
If it's clacking and knocking, think crate
motor or a VIN specific boneyard plug.
Chevy's suck!

There is a part 2 also
I don't own a GM so there is no reason for me to watch. But I think you probably helped the OP and the video was to the point and relatively well made, compared to many I've watched.

thanks for posting this is an intersting read. I will have to talk to the mechanic later
I am always somewhat skeptical. there are certain things i will do myself but i do not have all the tools or the time to tackle this one.
A little more background. A few months ago my oil pressure sending unit went and i did not have the time to change it so i brought it to Chevy to get fixed. I know dealerships are more money and i like to use small shops but i ended up there and they got it fixed and it did not break the bank. Fast forward a few months and recently i was getting a slight tick at times mostly on start up but it did sound more like a something caught in a belt or fan. I then brought it to a local mechanic that came recommended to me and they could not find an issue but did find my tensionor was worn which i suspected and they switched that out. The last week or two i am watching my oil gauge bounce around a bit well driving and thought that the oil sending unit was bad again so i brought it back the them and mentioned the tic and that is when they called me up and let me know the pump is bad. Most of the cost to fix it is labor.
My concern is i fix this and something else goes. The truck still drives great and would have no issue taking it on a road trip and it still looks great and everything still works. I am worried that if the oil pump went could the engine be next? I am going to mention that sluge in the intake tube.
On another note i went looking at new trucks today and drove one or two that i liked but not enough to justify the payment. These trucks have gone up quite a bit in msrp from what i bough mine for 8 years ago.
comparing a my truck to a comparable one on the lot is about 10k more comparing sticker to sticker.
Has it been maintained by the book? Has it been run like a Rented Mule? Has it towed heavy loads a lot? Has it had any overheating issues?
You also didn't say if it has OP gauge or Idiot Light, not that it really matters much. Many Idiot Lights only come on when pressure is abysmally low, sometimes less than 8 psi, allowing motor to run a long time w/o proper pressure. Am told Ford has used gauges that only register Normal or Zero!
Once had an OP sender fail in a way that let all the oil bleed out through it under pressure. Started smelling something burning, then Idiot Light came on, took a couple of minutes to get off highway - but the damage was done. Motors don't like to run w/low oil pressure.
200,000 miles is a reasonable maximum life expectancy & an oil pump is an unusual component to go.
In Europe Oil Analysis is commonly done. It detects/identifies which metals are wearing out.
If you want to keep it be prepared that more than an oil pump may be needed. While the pan is off, at the least I'd have new bearings put on crankshaft. Especially if there's any question about how long OP was running low.
even if you put a new crate motor in it and rebuild the trans, it's still cheaper than acquiring a new payment book. 300k on those trucks is common. most likely the screen is clogged , like mentioned in post #5.

Never added coolant
I don't change the oil myself as I just take it to a place and they rotate the tires and do an alignment when needed

Ugh, my 07 Silverado with 198000 miles just started doing the exact same thing last week.:banghead
